Table 4.
Average (s.e.m.) temperatures and VAS ratings chosen by HC, NP, and CP participants for perceived heat detection (HD), heat pain threshold (HPT), and heat pain tolerance (HPTol) during stimulation of the right (HC group) or clinically uninvolved volar forearm (patients) immediately before scanning.
| mean (s.e.m.) | ||||
|---|---|---|---|---|
| HC | NP | CP | ||
| HD | °C | 38.6 (0.37) | 41.2 (0.71)* | 40.6 (0.72)* |
| VAS | 2.35 (0.24) | 1.89 (0.21) | 2.98 (0.50)** | |
| HPT | °C | 46.4 (0.97) | 46.9 (0.66) | 47.2 (0.45) |
| VAS | 4.64 (0.35) | 4.70 (0.47) | 5.43 (0.41)** | |
| HPTol | °C | 49.4 (0.91) | 49.2 (0.55) | 50.0 (0.36) |
| VAS | 7.82 (0.23) | 7.55 (0.37) | 8.46 (0.38)** | |
higher than HC group (post hoc comparisons: p< 0.031 for NP and p< 0.004 for CP groups)
greater than HC and NP groups (post hoc comparisons: p<0.003 for NP and <0.015 for HC groups)
